Ohms Gain Calibration - Keysight Truevolt Series Operating And Service Manual

Ohms Gain Calibration

This calibration procedure applies to all models (34460A/61A/65A/70A).
Review Test Considerations
Configuration: 4-Wire Ohms
This procedure adjusts the gain for the 2-wire and 4-wire Ohms functions, and the offset compensated
Ohms function.
1. Configure each function and range in the order shown in the table below.
2. Apply the input signal shown in the Input column.
3. Enter the actual applied input resistance (see
ceeded message indicates success; if the display shows Calibration Step Failed, check the input value,
range, function, and entered calibration value and repeat the calibration step.
4. Repeat steps 1 through 3 for each gain calibration point shown in the table.
5. Store the new calibration constants (see
Each range takes less than 4 seconds to complete.
